Correcting scanned projector distortion by varying the scan amplitude
Briefly, in accordance with one or more embodiments, scanned beam projector may comprise a light source, a scan drive and a scanning platform to project an image onto a projection surface. The scan drive circuit is capable of at least partially correcting distortion in the projected image by varying an amplitude of the scan drive signal to at least partially compensate for the distortion in the projected image.

An apparatus for suppressing noise of a video signal. The apparatus includes: a difference-signal generation section generating a difference signal being a field or frame difference between the input and the output video signals; a noise compensation-signal generation section generating a noise compensation signal; a noise-compensation signal subtraction section; and a feedback-ratio control section, wherein the feedback-ratio control section includes a signal-level determination section determining a signal level of the difference signal for each area and detecting an abrupt change in an input signal, a count section counting the number of input fields or frames from the time of an abrupt change in a signal level to the subsequent abrupt change, and a feedback-ratio setting section setting a feedback ratio for the area in accordance with a count value, wherein the feedback-ratio setting section sets the feedback ratio such that the ratio gradually increases as the count value increases.
Method and apparatus for analog graphics sample clock frequency offset detection and verification
A method and apparatus for an analog-to-digital video signal converter. The converter is controlled by a clock with controllable frequency and phase for sampling an analog signal. A circuit corrects the clock frequency using a period of a columnar frame differences as a function of columnar location. The sampling clock frequency is changed by an amount dependent on the period of the columnar differences. A second measure of the difference between successive frames is computed for a sequence of clock phases. The frequency of the clock is verified using a characteristic of the second measure. The characteristic can be the ratio of the maximum to the minimum of the second measure over selected clock phases. Other characteristics can be used such as a difference of a maximum and a minimum measure.
Television receiving system
A television receiving system is disclosed, comprising an input terminal, a down-converter, an amplifier, an analog-to-digital converter (ADC), a demodulator, and an isolation circuit. The input terminal receives an RF signal. The down*converter, coupled to the input terminal, converts the RF signal to an intermediate frequency (IF) signal. The amplifier, coupled to the down-converter, amplifies the IF signal. The analog-to-digital converter, coupled to the amplifier, converts the amplified IF signal to digital data. The demodulator, coupled to the ADC, processes the digital data to generate baseband data. The isolation circuit, coupled between the amplifier and ADC, isolates the amplified IF signal from being affected by interference induced by the ADC.
